PER meter for measuring polarization extinction ratio (PER) of polarization-maintaining devices
This specialized polarization measurement instrument is designed for measuring the polarization extinction ratio (PER)) of polarization-maintaining devices, polarization angle of light sources, and PER of polarization-maintaining fibers and optical components. It can be used for various applications, including measuring the extinction ratio of polarization-maintaining fibers, devices, connectors, and performing polarization angle and axis measurements with remarkable precision and speed.
Features
- Wide dynamic range for PER measurement up to 50dB; maximum input power of 10dBm
- Simultaneous display of insertion loss, optical power, extinction ratio, optical axis angle, and polarization angle
- Supports free-space input
- Interchangeable connectors: FC, SC, LC
- Supports operation via an external PC
Typical Applications
- Monitoring of polarization-maintaining fiber splicing
- Testing Y-branch optical fiber gyroscope
- Alignment of polarization axis of optical device
- Measuring the extinction ratio of polarization-maintaining fibers
- Aligning polarization-maintaining fibers with laser light sources
- Testing PM couplers (PMC) and polarization beam splitters (PBS)
